did you clean the air filter? is there enough petrol? is the string or attached spring broken? do you have a choke?
most quads are key start so they use a key to start them and are called electric start quads and some quads use a pull start to start like a push lawnmower and are called pull start quads
Yes, a lawnmower can run on a bad battery if it has a pull-start or manual start option, as these methods do not rely on the battery. However, if the lawnmower is electric or requires the battery for ignition, a bad battery will prevent it from starting. In such cases, replacing or recharging the battery is necessary for proper operation.
switch on push primer bulb or choke the engine set throttle pull rope or turn key
It's a long piece of metal that's about 1/2 an inch thick and it's what pulls the pull cord back into the lawnmower after you pull it out.
To start a lawnmower, first ensure that it has enough fuel and that the oil level is adequate. Check that the spark plug is clean and properly connected. If it's a gas mower, engage the choke if the engine is cold, pull the starter cord firmly, and release the choke once it starts. For electric mowers, simply plug it in or ensure the battery is charged, then press the start button or pull the lever.
You might have a problem with the fly-wheel brake if it has one. Take the shroud off the top of the motor and check the cable to the brake if it is OK you already have the cover off so the recoil will be off too, check it and see if it is bound on something.
I've had this problem twice on two different motors both time it was the spark plug.
The engine floods and you have to wait for the lawnmower to drain before you start it up again or it might start smoking.
because ....well i got nothing I would check your float it might be sticking, fuel filter might be plugged. That depends on what type of lawnmower you are working on but it sound like a fuel problem to me .
As long as the battery in the lawnmower is a 12 Volt battery you will be fine.
the recoil spring is broken.
plug it in and push the on button
